I really love this girl. I have been with many before but she is the one I thought I am going to spend my life with. She was making me feel special and we were talking constantly every single day. I was feeling blessed with having her and was feeling like the luckiest man in the globe.

At beginning of our relationship we discussed about our past relationships. She said she was in a relationship with a married man right before me but she didn't knew the guy is married so when she got to know she stopped meeting him. She said she is in contact with him very rarely as a friend and colleague. When she told me about being in a relationship with that guy whom I know as well, it bothered me a lot. I know the guy and I know that he had played with many other girls as well. He is not honest with his wife and child's. He is one of most rubbish people I have ever come across. It bothered me as she was with someone as cheap as him but I tried to get over her past as I wanted to spent all my life with her.

As this guy was still in contact with her and they were talking too, I told her to stop it and delete the guy from her Facebook as he was commenting and flirting there as well as deleting his numbers. I also asked her to stop talking and meeting the guy as well. I told her he was married and he was cheating on his wife and in the mean time he lied to you so the guy is not even worth your friendship. She said as they have very mutual friend she can't delete him from Facebook but she will try not to talk to him and she promised to not meet him. Still I had a sense that she is hiding something from her past relationship and she don't want to tell me, so I asked her many times to tell me if she is hiding something but last time when I asked her the same question, she cried and told me that I don't trust her so I apologized and stopped asking that question and I thought I am being wrong and she is honest with me.

The other night she checked her Facebook from my computer and intentionally she did not logged out from there. And later when I was alone I went through her messages and started reading his Facebook conversation with that married guy. I got to know that my girlfriend knew the guy was married and she was asking him to divorce his wife and marry her which the guy didn't accepted. She even in somewhere wrote to him that she get jealous when she is thinking about he having sex with his wife and somehow indirectly asked the guy to stop having sex with his wife which again the guy rejected. Also I got to know she brought gifts when she was travelling to that guy's daughter. In some other parts of the conversation the guy asked her to take pictures for him and send to his email and she was doing so. She was also meeting with him and was talking sensual and sexual with him while knowing the guy was married and has two daughters. At somewhere of the conversation she is saying to the guy that his wife text her and asked her to stop talking with her husband and the guy says that she should not worry as his wife can't do anything. And my girlfriend again after on that guy's wife's request to not talk to her husband was talking and meeting him as it shows in Facebook conversation.

As I read in that conversation last time they had a chat in Facebook was about a month and half ago. She has talked about me with him and told him most of the things I told her and she has told the guy how I love her and hard feelings I have for her. Also that day she asked him to come and have lunch with her. It looks like she told all about me to make him jealous that she is with me.

So tomorrow of the day when I read this conversation I sms'ed and told her that because of an urgent work I am going out of city and in a rural area where I won't have any access to internet or phone for couple of days and will contact her as soon as I came back.

In last days I have been at home all alone and haven't visited anyone, didn't ate much as I can't and couldn't sleep as well. I am feeling disgusting that in return of trusting and loving her more then anything or anyone in the world she lied to me and hide such a big story from me. She even met the married guy when she promised to not meet him and telling me I am the only one in her life and how happy and special she feels with being mine. I am feeling like I have been used to make someone else jealous and I somehow think she even don't love me. Or maybe if she has feelings for me, they are not that serious that I was thinking and she was showing.

I am planning to call her and meet her tomorrow, but really don't know how to tell this stuff to her. I don't know if I am able to trust her anymore. I am not sure to give her a chance or not as I am sure she will ask for a second chance.

Please advice me and help me. I am feeling really bad for trusting her and loving her.

You shouldn't feel bad for loving or trusting her. She messed up! It sounds like she just used you until her married man came back to her. Break up with her and don't ever trust her again. You will heal over time and you will get over this.
